Detailed Implementation

[0025] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention.

[0026] Example

[0027] Reference Figures 1 to 8 A solid wood furniture processing coating spraying device includes a processing table 1, with an equipment housing 2 fixedly connected to the upper end of the processing table 1. A clearance hole 21 is provided on one side of the equipment housing 2, and a cabinet door is provided on the other side. A conveying component 3 is provided at the upper end of the processing table 1, extending into the equipment housing 2 through the clearance hole 21. A moving component 4 is provided between the inner walls of both sides of the equipment housing 2. Fixed components 5 are provided on both inner walls of the equipment housing 2, and the two sets of fixed components 5 are symmetrically arranged. A guide arc plate 6 is provided between the two sets of fixed components 5, and the moving component 4 penetrates through the guide arc plate 6. A spraying component 7 is provided through the upper end of the equipment housing 2, and the lower end of the moving component 4 is connected to the outer surface of the spraying component 7. The conveying component 3 is used to convey curved solid wood boards, and the spraying component 7 is used to spray coating onto the curved solid wood boards. The two sets of fixed components 5 are used to fix the guide arc plate 6, and the moving component 4 is used to adjust the horizontal position of the spraying component 7. The angle of the spraying component 7 can be adjusted by the guidance of the guide arc plate 6.

[0028] The moving component 4 includes a linear slide 41 fixedly connected between the inner walls of both sides of the equipment housing 2. The lower end of the linear slide 41 is rotatably connected to a telescopic rod 42, and the two shafts of the telescopic rod 42 cannot rotate relative to each other. It should be noted that the horizontal movement of the telescopic rod 42 by means of the linear slide 41 is a known prior art, and those skilled in the art are capable of conceiving of the specific structure.

[0029] The fixing component 5 includes a U-shaped fixing plate 51 that is threadedly connected to the inner wall of one side of the equipment housing 2 by bolts. An electric telescopic rod 52 is fixedly connected through one side of the U-shaped fixing plate 51, and one end of the electric telescopic rod 52 contacts the inner wall of the equipment housing 2. A clamping part 53 is fixedly connected to the other end of the electric telescopic rod 52. The horizontal position of the clamping part 53 can be adjusted by the electric telescopic rod 52.

[0030] Two sets of clamping plates 55 are embedded at intervals on one side of the clamping part 53, and two sets of support rods 54 are fixedly connected at intervals on the other side of the clamping part 53. Both sets of support rods 54 are movably connected through the U-shaped fixing plate 51. The clamping part 53 can be supported by the two sets of support rods 54, thereby enhancing the stability of the connection between the electric telescopic rod 52 and the clamping part 53. It should be noted that the clamping part 53 is a known prior art that uses the two sets of clamping plates 55 to move closer or further apart to achieve clamping. Those skilled in the art are capable of conceiving of the specific structure.

[0031] Two sets of engaging grooves 62 are spaced apart at both ends of the guide arc plate 6. Two sets of clamping plates 55 are respectively engaged with the two sets of engaging grooves 62. The guide arc plate 6 has a guide groove 61 running through it from top to bottom. The curvature of the guide arc plate 6 is the same as the curvature of the curved solid wood board to be sprayed. The arc length of the guide arc plate 6 is greater than the arc length of the curved solid wood board to be sprayed. The guide arc plate 6 can be clamped and fixed by the two sets of clamping plates 55. The engagement of the clamping plates 55 with the engaging grooves 62 can improve the stability of the clamping and prevent the guide grooves 61 from falling off.

[0032] The lower end of the telescopic rod 42 is threadedly connected to a screw 43, and the screw 43 passes through the guide groove 61. The outer surface of the screw 43 is threadedly connected to a first threaded ring 44 and a second threaded ring 45, and the opposite ends of the first threaded ring 44 and the second threaded ring 45 are set as arc surfaces. The second threaded ring 45 and the first threaded ring 44 are respectively in contact with the inner and outer sides of the guide arc plate 6. When the telescopic rod 42 moves, it will drive the screw 43 to move as well. Since the second threaded ring 45 and the first threaded ring 44 are respectively set on the inner and outer sides of the guide arc plate 6, the screw 43 will drive the telescopic rod 42 to rotate under the guidance of the guide arc plate 6.

[0033] The spraying assembly 7 includes a fixed tube 72 threaded to the lower end of the screw 43. One end of the fixed tube 72 is fixedly connected to a connecting hose 71, and the other end of the connecting hose 71 passes through the upper end of the equipment housing 2 and is connected to an external paint pumping device. Multiple sets of nozzles 73 are fixedly connected through the outer surface of the fixed tube 72 at intervals. The external paint pumping device can deliver paint from the connecting hose 71 to the inside of the fixed tube 72. The paint inside the fixed tube 72 can be sprayed out through the nozzles 73. When the screw 43 rotates, the fixed tube 72 will also move accordingly, thereby adjusting the spraying angle.

[0034] The conveying assembly 3 includes a lead screw drive unit 31 embedded in the upper end of the processing table 1. A placement platform 32 is provided on the upper end of the lead screw drive unit 31. Multiple sets of through holes are spaced apart near the two side edges of the upper end of the placement platform 32. Two sets of limiting strips 33 are spaced apart on the upper end of the placement platform 32. An embedded rod 34 is fixedly connected to the lower end of the limiting strip 33. Two sets of embedded rods 34 are spaced apart. The two sets of embedded rods 34 are movably engaged with the two sets of through holes. The engagement of the embedded rods 34 with the through holes can fix the limiting strips 33 on the placement platform 32. The position of the limiting strips 33 can be adjusted by simple insertion and removal operations, which is convenient to use. The two sets of limiting strips 33 can limit the curved solid wood board and prevent the curved solid wood board from shifting when moving. It should be noted that the horizontal sliding of the placement platform 32 by the lead screw drive unit 31 is a known prior art. Those skilled in the art can conceive of the specific structure.

[0035] In this invention, since curved solid wood panels are commonly used as furniture side panels, the convex side is set outwards. When the curved solid wood panel is fixed, the other side is completely invisible. Therefore, only the convex side of the curved solid wood panel needs to be painted. When painting the convex side of the curved solid wood panel, first place the curved solid wood panel with the convex side facing upwards on the placement table 32. Then adjust the positions of the two sets of limiting strips 33 to limit the curved solid wood panel. The position of the limiting strips 33 is adjustable so that the device can adapt to curved solid wood panels of different sizes. Then, the curved solid wood panel is transported to below the guide plate 6 by the screw drive 31, and the linear slide 41 enables extension and retraction. The rod 42 moves horizontally back and forth. Since the first threaded ring 44 and the second threaded ring 45 are respectively set on the outer and inner sides of the guide arc plate 6, the guide arc plate 6 guides the nozzle 73 to match the arc of the curved solid wood board to be tested when the nozzle rotates with the screw 43. The paint can be sprayed onto the curved solid wood board through the nozzle 73, and the spraying distance of the paint can be kept consistent. The spraying angle of the paint can be approximately the normal direction of the curved solid wood board to be tested, which can avoid the occurrence of spraying dead corners, making the coating thickness more uniform and improving the spraying effect. Moreover, a single reciprocation can cover the entire curved surface area, which can reduce the number of repeated spraying and reduce material waste.

[0036] When the curvature of the curved solid wood board to be processed changes, first open the cabinet door, then rotate the screw 43 to separate the screw 43 from the fixed tube 72 and the telescopic rod 42. Then remove the second threaded ring 45, so that the two sets of clamps 55 loosen the guide arc plate 6. Then pass the screw 43 through the guide arc plate 6 with the appropriate curvature, and then install the second threaded ring 45 on the screw 43. Then rotate the screw 43 to connect its upper and lower ends to the telescopic rod 42 and the fixed tube 72 respectively. Then clamp and fix the end of the guide arc plate 6 through the two sets of clamps 55. This completes the replacement of the guide arc plate 6, so that the spraying angle of the nozzle 73 can be adjusted according to the curvature of the curved solid wood board, improving the spraying effect. The spraying angle of the nozzle 73 can be adjusted according to the curvature of the curved solid wood board, improving the applicability of the device.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
